This application is a continuation-in-part of pending U.S. applicationSer. No. 11/223,296, filed Sep. 9, 2005, which is a continuation-in-partof pending U.S. application Ser. No. 10/612,478, filed Jul. 2, 2003,both of which are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates generally to gaming machines and, moreparticularly, to a gaming machine and a gaming system having a communityevent provided with a plurality of communal features.

BACKGROUND OF THE INVENTION

Gaming machines, such as slot machines, video poker machines, and thelike, have been a cornerstone of the gaming industry for several years.Generally, the popularity of such machines with players is dependent onthe likelihood (or perceived likelihood) of winning money at the machineand the intrinsic entertainment value of the machine relative to otheravailable gaming options. Where the available gaming options include anumber of competing machines and the expectation of winning each machineis roughly the same (or believed to be the same), players are mostlikely to be attracted to the most entertaining and exciting of themachines.

Consequently, shrewd operators strive to employ the most entertainingand exciting machines available because such machines attract frequentplay and, hence, increase profitability to the operator. In thecompetitive gaming machine industry, there is a continuing need forgaming machine manufacturers to produce new types of games, orenhancements to existing games, which will attract frequent play byenhancing the entertainment value and excitement associated with thegame.

One concept that has been successfully employed to enhance theentertainment value of a game is that of a “secondary” or “bonus” gamewhich may be played in conjunction with a “basic” game. The bonus gamemay comprise any type of game, either similar to or completely differentfrom the basic game, and is entered upon the occurrence of a selectedevent or outcome of the basic game. Such a bonus game produces asignificantly higher level of player excitement than the basic gamebecause it provides a greater expectation of winning than the basicgame.

Another concept that has been employed is the use of a progressivejackpot. In the gaming industry, a “progressive” involves the collectingof coin-in data from participating gaming device(s) (e.g., slotmachines), contributing a percentage of that coin-in data to a jackpotamount, and awarding that jackpot amount to a player upon the occurrenceof a certain jackpot-won event. A jackpot-won event typically occurswhen a “progressive winning position” is achieved at a participatinggaming device. If the gaming device is a slot machine, a progressivewinning position may, for example, correspond to alignment ofprogressive jackpot reel symbols along a certain pay line. The initialprogressive jackpot is a predetermined minimum amount. That jackpotamount, however, progressively increases as players continue to play thegaming machine without winning the jackpot. Further, when several gamingmachines are linked together such that several players at several gamingmachines compete for the same jackpot, the jackpot progressivelyincreases at a much faster rate, which leads to further playerexcitement. In existing progressive games, once a player at a firstgaming machine enters the progressive game, the players at the othergaming machines are not involved in the progressive game. In otherwords, the other players do not get the opportunity to participate inthe progressive game.

While these player appeal features provide some enhanced excitementrelative to other known games, there is a continuing need to develop newfeatures for gaming machines to satisfy the demands of players andoperators. Specifically, the current progressive games only provideenhanced excitement to the player invited to play for the jackpot. Thus,there is a need for engaging multiple players after one player enters acommunal game.

SUMMARY OF THE INVENTION

While the invention is susceptible to various modifications andalternative forms, specific embodiments have been shown by way ofexample in the drawings and will be described in detail herein. Itshould be understood, however, that the invention is not intended to belimited to the particular forms disclosed. Rather, the invention is tocover all modifications, equivalents, and alternatives falling withinthe spirit and scope of the invention as defined by the appended claims.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Turning now to the drawings and referring initially to FIG. 1, a videogaming machine 10 is depicted that may be used to implement the enhancedprogressive game according to the present invention. The gaming machine10 includes a video display 12 that may comprise a CRT, LCD, plasma,LED, electro-luminescent display, or generally any type of video displayknown in the art. In the illustrated embodiment, the gaming machine 10is an “upright” version in which the video display 12 includes a touchscreen and is oriented vertically relative to the player. It will beappreciated, however, that any of several other models of gamingmachines are within the scope of the present invention, including, forexample, a “slant-top” version in which the video display is slanted atabout a 30° angle toward the player, or gaming machines that includemechanical, rather than video, displays.

In one embodiment, the gaming machine 10 is operable to play a gameentitled WHO DUNNIT?™ having a mystery theme. The WHO DUNNIT?™ gamefeatures a basic game in the form of a slot machine with five simulatedspinning reels and a bonus game with selection options directing gameactivities on the video display 12. Such a gaming machine is disclosedin detail in U.S. Publication No. US 2002/0090990 A1, which isincorporated herein by reference in its entirety. It will beappreciated, however, that the gaming machine 10—may be implemented withgames other than the WHO DUNNIT?™ game and/or with several alternativegame themes.

FIG. 2 is a block diagram of a control system suitable for operating thegaming machine 10. Coin/credit detector 14 signals a CPU 16 when aplayer has inserted a number of coins or played a number of credits.Then, the CPU 16 executes a game program which causes the video display12 to display the basic game that includes simulated reels with symbolsdisplayed thereon. The player may select the number of paylines to playand the amount to wager via touch screen input keys 17. The basic gamecommences in response to the player activating a switch 18 in a lever orpush button, causing the CPU 16 to set the reels in motion, randomlyselect a game outcome, and then stop the reels to display symbolscorresponding to the pre-selected game outcome. Preferably, certainbasic game outcomes cause the CPU 16 to enter a bonus mode, which causesthe video display 12 to show a bonus game, as is known in the art.

A system memory 20 stores control software, operational instructions,and data associated with the gaming machine 10. In one embodiment, thesystem memory 20 comprises a separate read-only memory (ROM) andbattery-backed random-access memory (RAM). It will be appreciated,however, that the system memory 20 may be implemented on any of severalalternative types of memory structures or may be implemented on a singlememory structure. To provide gaming functions, the CPU 16 executes oneor more game programs stored in a computer readable storage medium, inthe form of the system memory 20. A payoff mechanism 22 is operable inresponse to instructions from the CPU 16 to award a payoff of coins orcredits to the player in response to certain winning outcomes which mayoccur in the basic game or bonus game. The payoff amounts correspondingto certain combinations of symbols in the basic game are predeterminedaccording to a pay table stored in system memory 20. The payoff amountscorresponding to certain outcomes of the bonus game are also stored insystem memory 20.

The gaming machine 10 of FIGS. 1 and 2 is a gaming terminal thatreceives inputs, randomly selects outputs and displays outputs, ascontrolled by the internal CPU 16. It will be appreciated, however, thatthe present invention can be used by gaming terminals controlled byexternal CPUs.

While the gaming machine 10 of FIGS. 1 and 2 has been described withrespect to providing a player a basic game and a bonus game, the gamingmachine 10 can be connected to a progressive game to which severalgaming machines are linked. This gaming network and, in particular, thenovel side wagering feature that can be activated by the player of thegaming machine 10 will be described below with reference to FIGS. 3-7.

Referring now to FIG. 3, a gaming system 28 of gaming machines 10 a, 10b, 10 c, 10 d is shown. The four gaming machines 10 a, 10 b, 10 c, 10 dare of the type described above in relation to FIGS. 1 and 2. The fourgaming machines 10 a, 10 b, 10 c, 10 d are interconnected and includedunder signage 30. The signage 30 includes a game screen 32 fordisplaying the progressive game which, in this embodiment, is theMONOPOLY ONCE AROUND™ game, and at least one jackpot screen 34displaying a plurality of dollar amounts for a multi-level progressivegame. In this embodiment, there are three dollar amount levels: a MiniJackpot, a Maxi Jackpot, and a Mega Jackpot. In other embodiments, theremay be any number of progressive jackpots.

The signage 30 includes a signage controller 36 that is connected toeach of the four gaming machines 10 a, 10 b, 10 c, 10 d. The signagecontroller 36 transmits information to and receives information from theCPU 16 (FIG. 2) in each of the four gaming machines 10 a, 10 b, 10 c, 10d throughout the game. The gaming system 28 allows for various aspectsof the gaming machines 10 a, 10 b, 10 c, 10 d, such as playingprogressive games to be controlled through the signage controller 36 inthe signage 30. Thus, all of the gaming machines 10 a, 10 b, 10 c, 10 dare linked to the progressive game.

Turning now to FIG. 4, the operation of the progressive game of thegaming system 28 will be described. Reference to FIGS. 5-8 will be madeto best describe this operation. In step 60, a player at the gamingmachine 10 begins a game by any conventional method (e.g., insertingcoins or using credits). Each gaming machine 10 a, 10 b, 10 c, 10 d hasa basic game that involves a player choosing a number of paylines toplay and choosing a wager to place on each payline. In some embodiments,there are a maximum of nine paylines. After choosing how many paylinesto play, the player selects how many credits (e.g., 1-5) to wager oneach payline. Any player who plays the maximum number of paylines—in thecase of the WHO DUNNIT™ gaming machine 10, nine paylines—is eligible tobe invited to play in the progressive game. At step 62, it is determinedif the progressive game has been randomly triggered by the CPU 16 of thegaming machine 10. This happens when a start progressive outcome, e.g, acombination of jackpot signals, occurs on the screen. If the progressiveoutcome is not reached, then the gaming machine 10 continues to operatenormally. Thus, the player continues to choose the wager amount for eachline, spins the reels, and any pay out or bonus games are playednormally. Once the game ends, the player is either paid out or morecoins/credits are requested for another game.

If, at step 62, one of the gaming machines 10 a—which will be referredto as the progressive play gaming machine 10 a—has been selected for theprogressive game, the basic game initially continues as normal, with theplayer playing the basic game and any bonus games. The CPU 16 of theprogressive play gaming machine 10 a sends a signal to the signagecontroller 36 that the progressive game has been activated. After thebasic game and bonus game have finished, at step 64, the player isnotified that the progressive game has been triggered (as shown in FIG.5).

In this embodiment, the progressive game is the MONOPOLY ONCE AROUND™game, which has a board game (e.g., MONOPOLY) theme and is implementedon the game screen 32 and video display 12 of all of the gaming machines10 a, 10 b, 10 c, 10 d. The board game defines a plurality of stationsor squares about a game board traversable by a game token, or token“identifier” indicating the position of a token, or player. For example,in one embodiment, a token “identifier” comprises an illuminated stationof the game screen 32 indicating the position of a token. Hereinafter,references to displaying the position of a token, or player, shall beunderstood to mean the display of either an actual game token or a tokenidentifier on a game board or portion thereof.

When the player enters the progressive game at step 64, the videodisplay 12 of the progressive play gaming machine 10 a instructs theplayer to select a token 40 (shown as a “SHOE” in FIGS. 7 and 8). In theMONOPOLY ONCE AROUND™ game, a screen may be displayed that shows ananimated Rich Uncle Pennybags symbol above a selection of MONOPOLYtokens 40 (e.g., “CAR,” “DOG,” “HORSE,” “SHOE” and “HAT”), and theplayer is prompted to select one of the game tokens 40. Such a methodand others are disclosed in U.S. Pat. No. 6,315,660, which isincorporated herein by reference in its entirety.

Also at step 64, the signage controller 36 sends a side wager inquirysignal that notifies the players at other gaming machines 10 b, 10 c, 10d in the system 28—hereinafter referred to as the side wager gamingmachines 10 b, 10 c, 10 d—that someone is entering the progressive game.

Then, at step 66, a screen is displayed on the video display 12 of theside wager gaming machines 10 b, 10 c, 10 d, giving the other playersthe opportunity to make side wagers on the stations of the game boardwhich the player predicts will be landed on during the progressive game.The side wagerers are given a particular amount of time (e.g., 30seconds) to make any side wagers. The time to make a side wager may becounted down by a clock on the display 12 of the side wager gamingmachines 10 b, 10 c, 10 d. The increments of the side wagers which maybe made on the various stations may be varied according to the gameprogram. For example, in the MONOPOLY ONCE AROUND progressive game, theplayer has the opportunity to “build” houses (make side wagers) on theproperties of the MONOPOLY board which the player predicts will belanded on during the progressive game. The amount of the side wagercorresponds to the “cost” of the houses built on the various properties,which generally varies according to the property selected.

While still at step 66, and after the selection of a property, thesignage controller 36 operates to display a property deed 44 (FIG. 6)corresponding to the selected property on the video display 12 ofwhichever side wager gaming machine 10 b, 10 c, 10 d that is making thewager. In FIG. 6, the property deed shown on the video display 12 of theside wager gaming machines 10 b, 10 c, 10 d is “Baltic Avenue,” thusindicating that the player has elected to build houses on Baltic Avenue.More specifically, the player has identified the “Baltic Avenue” stationas a predicted landing position of the token 40. The player buildshouses on the selected property by any number of methods, includingtouching the deed 44 or touching a specific key 42. The cost of thehouses may vary depending on the property, such as disclosed in U.S.Pat. No. 6,315,660, which was incorporated by reference above.

While still at step 66, the cost of the houses is subtracted from thecredits previously earned or paid into the side wager gaming machine 10b, 10 c, 10 d by the player. In one embodiment, the player may insertcoins or bills into the side wager gaming machine 10 b, 10 c, 10 d atany time during display of the screen shown in FIG. 6 to increase thecredits available for building houses. Various keys 46, 48 are providedto allow the players to clear their side wagers should they desire to doso before the beginning of the progressive game. Once the side wagersare made, a side wager response signal is transmitted from the sidewager gaming machine 10 b, 10 c, 10 d to the signage controller 36indicating that the side wager has been made.

Also occurring at step 66, the video display 12 displays a number ofhouse and hotel icons corresponding to the number of houses built oneach selected property. In FIG. 6, for example, the video display 12shows four green house icons and a red hotel icon represents the fifthwager placed on Baltic Avenue. The displayed property deed 44 identifiesthe cost per house (e.g., credits for Baltic Avenue) and the pay valueof landing on the property (e.g., 125 credits for Baltic Avenue, withfive houses).

At step 68, once the player of the progressive play gaming machine 10 a(FIG. 3) selects a token 40 and all side wagers have been placed, thesignage controller 36 displays a portion of the game board on the videodisplay 12 of all of the gaming machines 10 a, 10 b, 10 c, 10 d with theselected token 40 on a starting station of the game board. The signagecontroller 36 also illuminates the starting station on the game screen32. For example, in the MONOPOLY ONCE AROUND™ game, the starting stationis the “GO” square. The signage controller 36 then randomly selects aninteger movement value defining a number of stations or steps which thetoken 40 is to be moved from the GO square.

In one embodiment, the player “rolls” a pair of dice 49 (FIG. 3) bytouching a “Roll Dice” key 50 or “Auto Roll” key 52 on the video display12 of the progressive play gaming machine 10 a. At step 70, token 40(FIGS. 7 and 8) is advanced across the game board according to the rollof the dice. On the game screen 32 (FIG. 3), movement is illustrated bythe illumination, in step-wise fashion, of the appropriate stations(squares) on the game board (e.g., MONOPOLY board) from the previousposition to the position determined by the roll of dice. On the videodisplay 12 of the gaming machines 10 a, 10 b, 10 c, 10 d, movement isillustrated by the selected game token (e.g., “SHOE”) moving, one spaceat a time, a corresponding number of spaces on a scrolling portion ofthe game board. The landing of the token 40 on a particular square orstation of the game board constitutes an event in the progressive game.

At step 72, after each roll, the player of the progressive game machine10 a is awarded a point amount that corresponds to the square. In theMONOPOLY ONCE AROUND™ game, if the token 40 lands on a “Chance” or“Community Chest” station (square) during the progressive game, theplayer playing the progressive game receives an award of a fixed numberof points (e.g., “BANK ERROR IN YOUR FAVOR, 100 points), or they canmove the player to a new space (e.g., GO BACK THREE SPACES). If thetoken 40 lands on a property, various points are awarded to the player.In some embodiments, the points awarded may be dependent on the value ofthe property, as described in U.S. Pat. No. 6,315,660.

Then, at step 72, the signage controller 36 compares the event to theposition(s) wagered on by the side wager gaming machines 10 b, 10 c, 10d and, if the event matches any of the position(s) wagered on, theplayer who made the side wager is paid an amount of coins or credits, asappropriate, corresponding to the cost of building the house(s) on thatproperty.

Next, at step 74, the signage controller 36 determines if the player hasmoved once around the entire board. If the answer is “no,” the programreturns to step 68 and the dice is rolled, creating a new event. If theanswer is “yes,” then the progressive game has ended and the programmoves to step 76 and awards credits to the player of the progressivegame.

In a preferred embodiment, at step 76, the payout amount that theprogressive game player wins is dependent upon the amount of points thatwere earned. In some embodiments, the progressive game may comprisemultiple jackpots of varying amounts. The more points that the playeraccumulates during the game, the more credits or money that is paid tothe player at the end. As shown in FIG. 3, the gaming system 28 hasthree payouts, or levels: a mini progressive, a maxi progressive, and amega progressive. The mini progressive pays out when a player earnsbetween 0 and 499 points during the progressive game, the maxiprogressive pays out to players who have earned between 500 and 999points, and the mega progressive only pays out to players who earn morethan 1000 points during the progressive game.

Once one of the levels of a progressive game has been paid out, thatlevel resets itself to the base amount. The other progressives that didnot pay out keep increasing until someone wins that progressive jackpot.The progressive jackpots are created by a base amount being put into thepot (e.g., $1,000 for the mini, $3,000 for the maxi, and $5,000 for themega). Then, every time one of the gaming machines 10 a, 10 b, 10 c, 10d in the system 28 is played, a percentage of the amount wagered isplaced into each of the progressives. In some embodiments, 1% may go tothe mini progressive, ½% to the maxi progressive, and ¼% to the megaprogressive. Because the maxi progressive and the mega progressivepayouts less often than the mini progressive, less money needs to go tofund these progressives.

After the credits are all awarded and the progressive has been reset,the program goes back to step 60, with a player playing the maximumnumber of paylines on the machine.

In another embodiment, the present invention may operate to allow otherplayers to make side wagers when one player has reached any specialgaming session. The special gaming session is any game other than thebasic game depicted in FIG. 1. For example, the special gaming sessionmay be a bonus game or a progressive game.

In some embodiments, only the side wager gaming machine 10 b, 10 c, 10 ddisplays the wager made. A screen displaying the game board may appearon the machine with houses placed on the property on which the playerwagered. In other embodiments, the side wagers may be displayed on thegame screen 32, with different color houses representing the differentplayers. In either embodiment, multiple players can place side wagers onthe same property. For example, two different players can each placefive houses on Baltic Avenue.

In an alternative embodiment, the person playing the progressive gamecan also make side wagers on the various events of the game. Theprogressive play gaming machine 10 a would then perform all of thefunctions described above with respect to the side wager gaming machines10 b, 10 c, 10 d. The display 12 in FIG. 8 would then also depict theside wagers placed by the person playing the progressive gaming machine10 a.

In some embodiments, the amount of points awarded for the “Chance” or“Community Chest” cards is dependent on the amount wagered by the playerper each payline in the basic game. A player who wagered the minimumamount per each payline will receive fewer points than a player whowagers the maximum amount per each payline, even if they draw the samecard. For example, the card “Grand Opera Opening” has a payout of 9credits. In this embodiment, that may be the payout for someone whowagered 1 out of a possible 5 credits. For someone who wagered 5credits, the payout may be 45 credits. Also, the card marked “Go BackThree Spaces” may have multiple space numbers depending on the amountwagered. For example, if only 1 credit is wagered, the card may read “GoBack Two Spaces,” but if the player wagered the maximum amount, the cardmay read “Go Back Five Spaces,” thus giving that player more chances toland on property and earn more points.

In another alternative embodiment, the side wager gaming machines 10 b,10 c, 10 d are offered the chance to place a wager on what the outcomeof the progressive game will be. In other words, the side wager gamingmachines 10 b, 10 c, 10 d can send a side wager response signal placinga wager on whether the player of the progressive play gaming machine 10a will win the mini jackpot, the maxi jackpot, or the mega jackpot. Theside wager gaming machines 10 b, 10 c, 10 d will be credited asdescribed above if the predicted outcome matches the outcome of theprogressive game.

In another alternative embodiment, at step 62 in FIG. 4, it is thesignage controller 36, not the CPU 16, that randomly starts theprogressive game. In this embodiment, the signage controller 36 sends asignal to the CPU 16 of the next gaming machine 10 that places a wagerthat the progressive game has been triggered. The rest of the gameproceeds as described above.

Referring now to FIG. 9, a gaming system 128 comprising a bank of gamingmachines 110 a-f is illustrated in accord with one embodiment of thepresent invention. The gaming machines 110 a-f may be of the typedescribed above with respect to FIGS. 1-2 or any other type of gamingmachine suitable for operating a wagering game. The gaming machines 110a-f are interconnected and included under signage 130. The signage 130includes a community display 132 for displaying a community eventthereon. According to one embodiment, the community display 132 is oneor more plasma displays visible to each player seated at the bank ofgaming machines 110 a-f.

The signage 130 includes a signage controller (not shown) similar inoperation to the signage controller 36 described above with respect toFIG. 3. The signage controller is connected to one or more of the gamingmachines 10 a-f and transmits information to and receives informationfrom the CPU (FIG. 2) in one or more of the gaming machines 110 a-fthroughout the wagering game. The gaming system 128 allows for variousaspects of the gaming machines 110 a-f, such as playing communal games,to be controlled through the signage controller in the signage 130.

According to one embodiment, a community event includes a plurality ofelements displayed on the community display 132. One or more of theplurality of elements has a communal value associated therewith. Thecommunal value represents the base award provided to a playerparticipating in the community event when a particular element isearned. As will be discussed below with respect to FIGS. 11 a-c, thecommunal value may be increased for each player participating in thecommunity event based on the value-enhancement parameter that has beenearned by the individual player. The community event may be, forexample, a MONOPOLY ONCE AROUND™ game, a different MONOPOLY® game, orany other type of communal game.

The community event may be initiated by achieving a winning combinationof symbols on any of the gaming machines 110 a-f within the bank or bythe signage controller independent of the symbols appearing on thegaming machines 110 a-f. Once a community event has been initiated, aplurality of players at the bank of gaming machines 110 a-f are selectedto participate in a communal wagering game. According to one embodiment,the players are selected based on their time eligibility as determinedby their recent wager history.

Time eligibility is measured using, for example, a time slice, which isthe amount of time that a wagered amount gives eligibility to the playerfor entry into the communal wagering game. A time-slice counter is usedto increment and/or decrement time slices for increasing and/ordecreasing the time that the player is eligible to participate in thecommunal wagering game. If the player has eligibility during anincrement of time when the community event is triggered, then the playeris allowed to play the communal wagering game. The player may also beprovided with a value-enhancement parameter within the communal wageringgame based on the player's betting history, as will be discussed belowwith respect to FIGS. 11 a-c. The value-enhancement parameter mayinclude a plurality of levels that can be earned by the player bywagering on the basic wagering game. Each level has a certain maximumnumber of purchasable time slices.

FIGS. 10-13 b illustrate various aspects of a communal bonus gameoperable on the above-described gaming system 128. In the illustratedembodiments, a MONOPOLY ONCE AROUND™ game is used as an example of onetype of communal game that may incorporate the various aspects of thepresent invention. However, it should be noted that other game types,styles, and features may be utilized in accordance with the presentinvention.

Referring now to FIG. 10, a plurality of elements (e.g., a plurality ofstations 152) are displayed on the video display 112. In the illustratedembodiment, the stations 152 are aligned to form a trail 150. Once aplurality of players have been selected to participate in the communalwagering game, each player is provided an opportunity to select aplurality of deeds 160 (e.g., up to 5) that represent individualstations 152 along the trail 150. As illustrated in FIG. 10, the playerhas selected a first deed 162 that represents “VERMONT AVENUE.”

The various deeds 160 are arranged so as to allow the player to selectthe deeds 160 by utilizing the touch screen input keys 17 (FIG. 2) orother input means. In some embodiments, the player is given apredetermined length of time to select the required number of deeds 160.If the player fails to select the required amount of deeds 160 in theallotted period of time, the gaming system 128 automatically selects theremaining number of deeds 160 for the player.

One method to facilitate automatic selection is to indicate to a playerwhich of the deeds 160 will be selected for the player once the timeexpires. For example, in the illustrated embodiment, deeds 166 a, 166 b,and 166 c are slightly raised from the other deeds 160. The raised deeds166 a-c indicate to a player that these deeds 166 a-c will be selectedby the gaming system 128 for the player if the player does not chooseotherwise. In addition to the raised deeds 166 a-c, a highlighted,raised deed 164 may also be provided to indicate that the next playerselection will void the automatic selection of the highlighted, raiseddeed 164 by the gaming system 128.

Thus, for embodiments where five deed selections are required, fivedeeds among the plurality of deeds will be randomly selected and raisedby the gaming system 128, with one of the raised deeds beinghighlighted. Once a player chooses a first deed, the highlighted, raiseddeed will be lowered and one of the remaining four raised deeds willbecome the highlighted, raised deed. This process will continue untilall five deeds are selected by the player or the predetermined timeperiod has expired—at which time the remaining raised deeds will beautomatically selected for the player.

One or more of the stations 152 has a communal value 168 associatedtherewith. When a deed 160 representing a particular one of the stations152 is selected, the communal value 168 for that particular station 152is increased for the player that selected the deed 160. Thus, theselection of one or more deeds allows a player to increase the awardvalue of a particular station 152 if the station 152 is earned duringthe communal wagering game.

Referring also to FIGS. 11 a-c, another method for enhancing, anddisplaying the enhanced, award values is illustrated, according to oneembodiment of the present invention. FIG. 11 b illustrates a communitydisplay 132 for displaying the above-described communal wagering game.The community display 132 displays the trail 150 as well as the communalvalues 168 associated with one or more of the plurality of stations 152.The communal values 168 vary for the plurality of different stations 152included within the trail 150.

As discussed above, when the community event is initiated, adetermination is made as to which players at the plurality of gamingmachines 110 a-f are eligible to participate in the communal wageringgame. A determination is also made as to whether to apply avalue-enhancement parameter to the player's gaming machine and if so,what the value of the parameter will be. For example, in one embodimentthe player's betting history prior to the initiation of the bonus eventwill determine the value of the player's value-enhancing parameter. Inother embodiments, the length of the gaming session, total creditswagered, speed of play, credits earned, etc. can be used to determinethe player's value-enhancing parameter.

The value-enhancing parameter enhances the communal values 168associated with the stations 152 to arrive at a player value for thestations 152. The value-enhancing parameter can be, for example, amultiplier that is applied to each of the communal values 168 toincrease the communal values 168 by the particular multiplier value(e.g., 1×, 2×, 3×). According to other embodiments, the value-enhancingparameter is a predetermined amount or selected from a predeterminedrange of amounts.

As illustrated in FIGS. 11 b-c, the player values 172 a, 172 b areincreased based on the determined value-enhancement parameter for eachplayer. As illustrated in FIG. 11 b, the value-enhancement parameter isa 5× multiplier and the first player values 172 a displayed on the firstvideo display 112 a are five times greater than the communal values 168displayed on the community display 132 in FIG. 11 a. Similarly, in FIG.11 c the value-enhancement parameter is a 3× multiplier and the secondplayer values 172 b displayed on the second video display 112 b arethree times greater than the standard communal values 168.

In addition to the value-enhancement parameters increasing the communalvalues 168, a plurality of markers 174 (e.g. hotels) are utilized todesignate the stations 152 for which deeds 160 were previously selectedby the player. The player values 172 a, 172 b for those stations 152 forwhich the player selected a deed 160 (FIG. 10) are further increased. Inthe illustrated example, the selection of a deed 160, as described withrespect to FIG. 10, results in a 2× multiplier being applied to thecommunal value 168 for the selected properties. This 2× multiplier is inaddition to the value-enhancing parameters that were previously appliedto the communal values 168, and creates an added-value station along thetrail 150. Each of the stations 152 designated with a marker 174 arereferred to as added-value stations.

As discussed above with respect to FIG. 4, in the MONOPOLY ONCE AROUND™game, a game token 140 begins at a first station along a trail, such asthe GO station on a MONOPOLY® board. The signage controller randomlygenerates a length of advancement (e.g., a number of spaces) that thetoken 140 will move along the trail 150. The signage controllercontinues to randomly generate lengths of advancement until the token140 has completed a single circuit around the trail 150 so as to passthe GO station.

As illustrated in FIGS. 11 a, the token 140 has advanced to “ORIENTALAVENUE” and the associated payout deed 170 is displayed to the player onthe community display 132. The payout deed 170 displays the communalvalue 168 for the particular station 152 to the players, while eachplayer is awarded their respective player values 172 a, 172 b for thestation 152. Once the player values 172 a, 172 b have been awarded, thecontroller generates another length of advancement and the token 140moves further along the trail 150. It should be noted that each playerparticipating in the communal wagering game may be prompted to select anindividualized token 140 a, 140 b (FIGS. 11 b-c) that is displayed onthe first and second video displays 112 a, 112 b, respectively.

The individualized tokens 140 a, 140 b may also be utilized to representthe player on the community display 132. For example, the communitydisplay may include a plurality of player-award meters 190 a; 190 b usedto display the award accrued by the individual players. The player-awardmeters 190 a, 190 b are also displayed on the first and second videodisplays 112 a, 112 b respectively. A communal-award meter 194 fordisplaying the total award provided during the communal wagering game isalso provided on the community display 132. The communal-award meter 194displays the overall value of the awards that have been earned by theplayers over the course of the communal wagering game.

The first and second video displays 112 a, 112 b include a plurality ofadvancement identifiers 196 a-j indicating the number of stations 152the token 140 must advance to “land on” the indicated station 152. Forexample, the first video display 112 a has advancement identifiers 196a-e identifying various stations 152 along the trail 150.

According to one embodiment, the advancement indicators 196 a-j identifyall of the marked properties and all of the special-event properties (aswill be discussed with respect to FIGS. 12-13 b below) reachable withinthe next length of advancement, which, in the illustrated example, istwelve stations (e.g., one roll of two dice). The advancement indicators196 a-j may assist in allowing a player to quickly identify what lengthof advancement they desire on the next “roll.”

Turning now to FIGS. 12-13 b, a plurality of special-feature elementswill be detailed with respect to various embodiments of the presentinvention. FIG. 12 illustrates special-feature elements that award theparticipating players in the communal wagering game an award that is notassociated with the special-feature element itself. When aspecial-feature element is achieved, a special-feature event isinitiated and displayed on a community display 232.

For example, when a first special feature 260 is initiated (e.g., the“ELECTRIC COMPANY” feature), a station designator 262 appears within thetrail 250. The station designator 262 moves around internal portion ofthe trail 250 pointing from station 252 to station 252 until finallyselecting one of the other stations 252 along the trail 250. Once astation 252 has been selected by the first special feature 260, theplayer values associated with that station 252 are awarded to theindividual players. In some embodiments, the player values are furtherincreased when a special feature is initiated. For example, the firstspecial feature 260 can apply an additional multiplier (e.g., a 2×multiplier) to the communal values 168 (FIG. 11 a) and award theresulting player values.

A second special feature 270 (e.g., the “railroad” feature) can also beinitiated. When a token 240 lands on a second special-feature elementthe second special feature 270 is initiated. The initiation of thesecond special feature 270 causes a locomotive 272 positioned on arailroad track 274 to be displayed on the community display 232. Thelocomotive 272 moves along the railroad track 274 and transports thetoken 240 back along the trail 250. The locomotive 272 eventually stopsand the token 240 is “dropped off” at the station 252 where thelocomotive 272 stops. The players are then awarded their individualplayer values associated with the station 252.

In addition, a third special feature 280 (e.g., the “WATER WORKS”feature) can also be initiated. The initiation of the third specialfeature 280 causes a pipe 281 to form over a plurality of stations 252.The pipe 281 includes a valve 282 located at each station 252. A bulge284 in the pipe 281 indicates where the token 240 is moving within thepipe 281. The bulge 284 continues to move along the pipe 281 until oneof the valves 282 opens and the token 240 is released at a particularstation 252. The players are then awarded their individual player valuesassociated with the station 252.

In both the second special feature 270 and the third special feature 280the token 240 is actually moved along the trail 250, while in the firstspecial feature 260, the token 240 remains stationary and only thestation designator 262 moves. In some embodiments, the second specialfeature 270 and the third special feature 280 are capable of moving thetoken 240 anywhere along the trail 250 in either direction. In otherembodiments, however, the second special feature 270 and the thirdspecial feature 280 are limited in the range and/or direction they canmove the token. For example, in some embodiments, the second specialfeature 270 can only move the token 240 back in the direction from whichit came and only regress the token 240 five or less stations 252. Insome embodiments, the third special feature 280 can only advance thetoken 240 and only for up to twelve stations 252 (e.g., one roll of thedice).

Referring also to FIGS. 13 a-b, a fourth special feature is displayed ona community display 332. The fourth special feature is anelimination-type feature that includes a plurality of value-bearingsymbols 350 displayed on the community display 332, as illustrated inFIG. 13 a. The value-bearing symbols 350 are removed one at a time—asillustrated in FIG. 13 b—until only a single value-bearing symbol 350remains. The value associated with the single remaining value-bearingsymbol 350 is then awarded to each of the players participating in thecommunal wagering game. The value associated with the single remainingvalue-bearing symbol 350 may be enhanced by the value-enhancementparameters as discussed above. In some embodiments of the presentinvention, the elimination-type feature is initiated when the token 140(FIG. 11 a) advances to “CHANCE,” “COMMUNITY CHEST,” or “FREE PARKING.”The values associated with the plurality of value-bearing symbols 350may vary depending on which of the stations initiates the feature.

As discussed above, the community event may be, for example, a MONOPOLYONCE AROUND™ game, a different MONOPOLY® game, or any other type ofcommunal game. Additionally, one or more of the above described specialfeatures within the MONOPOLY ONCE AROUND game may be independentcommunity events. In alternative embodiments, one or more of the specialfeatures are both events within the MONOPOLY ONCE AROUND™ game as wellas being independent community events.

The community event may be triggered by achieving a winning combinationof symbols on any of the gaming machines 110 a-f (FIG. 9) within thebank or by the signage controller independent of the symbols appearingon the gaming machines 110 a-f. Additionally, or alternatively, thesignage controller 36 (FIG. 3), or CPU 16 (FIG. 2) may randomly triggera community bonus event.

Once a community bonus event has been triggered, the signage controller36, CPU 16, or other controller randomly selects one of the plurality ofindependent community events to initiate. The randomly selectedcommunity event is then displayed on the community display 132 and aplurality of players at the bank of gaming machines 110 a-f are selected(e.g., by time eligibility) to participate in the randomly selectedcommunal wagering game. Alternatively, the community event may beselected based on the particular winning combination of symbols achievedduring play of the basic wagering game.

According to one embodiment, the plurality of community events includesthe MONOPOLY ONCE AROUND™ game and one or more of the above-describedspecial features as independent community events. According to stillother embodiments, the plurality of community events includes theMONOPOLY ONCE AROUND™ game, one or more of the above-described specialfeatures as independent community events, additional community events aswill be described below, or any combination thereof.

According to one particular embodiment of the present invention, theplurality of community events includes: (1) the MONOPOLY ONCE AROUND™game (FIGS. 10-13 b); (2) a “CHANCE” elimination-type community event(similar to the elimination-type feature illustrated in FIGS. 13 a-b);(3) a “COMMUNITY CHEST” elimination-type community event (similar to theelimination-type feature illustrated in FIGS. 13 a-b); (4) a “MR.MONOPOLY” community event (FIG. 14); (5) a “RAILROAD RICHES” communityevent (FIGS. 15 a-b); and (6) a “FREE PARKING” community event (FIGS. 16a-c). In this embodiment, the signage controller 36, CPU 16, or othercontroller randomly selects one of the six independent community eventsto initiate.

The individual community events may be weighted differently such thatone or more of the community events are more likely to be initiated thananother one of the community events. For example, the MR. MONOPOLYcommunity event may be weighted differently than the MONOPOLY ONCEAROUND™ game such that the MR. MONOPOLY game is randomly selected moreoften (e.g., three times more often) than the MONOPOLY ONCE AROUND™game. Alternatively, the individual community events may be configuredsuch that each of the community events is initiated approximately thesame number of times as each of the other community events over time.

Turning now to FIG. 14, according to one embodiment, an increasing-awardcommunity event 400 adapted to be displayed on a community display(e.g., community display 132 illustrated in FIG. 9) is illustrated. Inthe illustrated embodiment, the increasing-award community event 400 isa “MR. MONOPOLY” community event.

When the MR. MONOPOLY community event is initiated, MR. MONOPOLY 410appears on the community display (e.g., community display 132 in FIG. 9)and begins ladling gold coins 416 out of a pot 420 while a credit prize430 increases. The credit prize 430 continues to increase until MR.MONOPOLY 410 stops ladling coins 416 from the pot 420. After the creditprize 430 has been increased and the ladling stops, the credit prize 430is awarded to each of the players participating in the community event.In some embodiments, the credit prize 430 is increased by a player'svalue-enhancement parameter earned by playing the basic wagering game,as described above with respect to FIGS. 11 a-c.

Referring now to FIGS. 15 a-b, a value-selector community event 500adapted to be displayed on a community display (e.g., community display132) is illustrated, according to one embodiment of the presentinvention. In the illustrated embodiment, the value-selector communityevent 500 is a “RAILROAD RICHES” community event.

When the RAILROAD RICHES community event is initiated, a moveable stripof elements 510 (e.g., numbers, symbols, etc.) is moved through a frame520 that forms a selection area 530. The frame 520 is adapted tosurround one or more of the elements from the moveable strip of elements510. The selected elements are displayed within the selection area 530as the moveable strip of elements 510 is moved. As illustrated in FIG.15 b, the moveable strip of elements 510 has come to rest and theselection area 530 includes the number “783.” According to someembodiments, the selection of the number “783” awards 783 credits toeach of the individual players participating the value-selectorcommunity event 500 or may be split among the players. In someembodiments, the awarded credits are increased by a player'svalue-enhancement parameter earned by playing the basic wagering game.

In the illustrated embodiment, the moveable strip 510 is illustrated asbeing made up of a plurality of rail cars pulled by a locomotive 540.Each rail car includes three of the elements from the moveable strip510. In alternative embodiments, more or less elements are included ineach rail car while in other embodiments, the number of elements perrail car varies from car to car. According to some embodiments of thepresent invention, the size of the frame 520 varies as the moveablestrip 510 is moved along the display. Thus, the selection area 530 may,at times, include only a single element while, at other times, includeany plurality of elements from the moveable strip 510.

Turning now to FIGS. 16 a-c, a progressive community event 600 isillustrated, according to one embodiment of the present invention. Theprogressive community event 600, according to the illustratedembodiment, is a “FREE PARKING” community event having four potentialaward levels that may be selected. The first award level 610 is thesmallest, and is represented by a first symbol 612, the “DOG,” in theillustrated embodiment. The current value for the first award level 610is displayed within a first-level meter 614. A plurality of first-levelselectable symbols 616 are represented along a selection chain 650.

A second award level 620, generally having a larger value than the firstaward level 610, is represented by a second symbol 622 (e.g., a “CAR”).The current value for the second award level 620 is displayed within asecond-level meter 624. A plurality of second-level selectable symbols626 are represented along the selection chain 650. A third award level630, generally having a larger value than both the first award level 610and second award level 620, is represented by a third symbol 632 (e.g.,a “TOPHAT”). The current value for the third award level 630 isdisplayed within the third-level meter 634. A plurality of third-levelselectable symbols 636 are represented along the selection chain 650.

A fourth award level 640, generally having a larger value than the thirdaward level 630, is represented by a fourth symbol 642 (e.g., a“MONEYBAG”). The current value for the fourth award level 640 isdisplayed within a fourth-level meter 644. At least one fourth-levelselectable symbol 646 is represented along the selection chain 650.

Each of the award levels 610, 620, 630, 640 includes a progressive awardvalue that generally increases in value over time. According to someembodiments, the progressive award values increase each time theprogressive community event 600 is initiated. According to otherembodiments, the progressive award values increase: each time anycommunity event is initiated; after a predetermined period of time;after a particular game outcome is achieved; after a particular amountof wagers are accepted; or by any other method sufficient to increasethe award values over time.

The selection chain 650 is illustrated as an arch surrounding a portionof the meters 614, 624, 634, 644. Each of the symbols 612, 622, 632, 642is represented along the selection chain 650. However, the number ofeach of the symbols is varied so as to make the selection of the firstsymbol 612 more likely than the selection of the second symbol 622 andso on. Thus, it should be apparent that the likelihood of achieving thefourth award level 640 is less than the likelihood of achieving thesecond award level 620.

When the progressive community event 600 is initiated, a singleselectable symbol is selected from the selection chain 650. Asillustrated in FIG. 16 b, a selected-symbol box 660 has been selectedfrom the selection chain 650. The selected-symbol box 660, in theillustrated example, indicates to a player that one of the plurality ofsecond-level selectable symbols 626 has been selected. An award meter670 is displayed to indicate the amount of the award that will beawarded to each of the players participating in the community event. Insome embodiments, the value within the award meter 670 is increased by aplayer's value-enhancement parameter earned by playing the basicwagering game.

Once a particular award level has been awarded, in this case the secondaward level 620, the award value resets to its predeterminedsecond-award-level minimum which, as illustrated in FIG. 16 c, is $10.00in this example. It should be noted that when a particular award valueis reset, the award value may, in fact, be lower than the award valuefor an award level beneath the reset award level. This is especiallytrue where a particular lower award level has not been selected for anextended period of time.

The progressive award values, in some embodiments, are not directlyincreased by the coin-in values to the gaming system 128 (FIG. 9). Forexample, the progressive award values may only be increased when any ofthe community events are triggered or initiated. As such, the value ofthe progressive awards are independent of the coin-in values and areinstead dependent on the number of times one of the community events isinitiated. In some embodiments, the progressive award values may beincreased based on the expected value for the community events as awhole, or based just on the expected value of the MONOPOLY ONCE AROUNDcommunity event.
